NPT stands for National Pipe Taper, the standard thread form used throughout plumbing, HVAC, and industrial piping systems in North America. This tap produces a 3\/8-inch nominal pipe thread at 18 threads per inch, creating a pressure-sealing taper that accepts standard NPT fittings. Plumbers, pipefitters, and HVAC technicians reach for this tool when threading ports, bosses, or new openings in pipe assemblies, manifolds, and equipment housings.\u003c\/p\u003e\u003cp\u003eThis tap is suited for use in residential and light commercial plumbing, gas line work, and HVAC refrigerant or hydronic piping applications where NPT-threaded connections are required. It is commonly used to thread steel, iron, brass, and similar materials. The 3\/8-18 NPT size is one of the most frequently encountered thread sizes in plumbing and gas distribution, appearing in shutoff valves, pressure gauges, sensors, and pipe nipple connections across a wide range of systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHigh-speed steel (HSS) construction provides durability and heat resistance during threading operations\u003c\/li\u003e\n\u003cli\u003e3\/8-18 NPT taper thread form produces pressure-sealing threads per ANSI\/ASME B1.20.1 standards\u003c\/li\u003e\n\u003cli\u003eTapered thread geometry provides leak-resistant joints when assembled with compatible NPT fittings\u003c\/li\u003e\n\u003cli\u003eImport designation offers a cost-effective option for general-purpose threading tasks\u003c\/li\u003e\n\u003cli\u003eMinimum order quantity of 1 allows single-unit purchase for service and repair use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for cutting 3\/8-18 NPT tapered pipe threads in steel, iron, brass, and similar machinable metals commonly found in plumbing, gas, and HVAC piping systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap is installed using a standard tap wrench or machine chuck rated for the tool diameter. Always apply a suitable cutting fluid when tapping ferrous materials to reduce heat buildup and extend tool life. Ensure the workpiece is securely clamped and the tap is started square to the hole to avoid cross-threading or tap breakage. Follow applicable codes such as the IPC or IFGC when threading connections in plumbing or gas piping systems.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-18 NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPT (National Pipe Taper)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.12 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: EAGLE CUTTING TOOL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: PT-3750-18-I\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233617609010,"sku":"PT-3750-18-I","price":22.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307623550.png?v=1780104773","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-pt-3750-18-i-hss-npt-pipe-tap-3-8-18","provider":"Voomi Supply","version":"1.0","type":"link"}
